How Affiliate Networks Actually Work: A Plain-English Explainer

Reader-supported publications like this one are funded through affiliate networks. Because we think readers deserve to understand how the money moves, this piece walks through what an affiliate network actually is and how a click on a link in one of our reviews turns into a small commission.

What an affiliate network actually is

An affiliate network is a marketplace and a tracking platform rolled into one. On one side, retailers and brands list offers — a commission rate, a cookie window, allowed promotional methods. On the other side, publishers (websites, creators, comparison sites) apply to promote those offers. The network sits in the middle and handles discovery, tracking and payments.

Tradedoubler, Awin, Impact, CJ Affiliate, ShareASale and Rakuten are the names most readers will run into. The underlying model is the same across all of them.

How tracking actually works

When a publisher places an affiliate link, that link routes through the network before landing on the retailer's site. The network stamps a click ID and drops a cookie. If the reader completes a qualifying action — usually a purchase — the retailer's site fires a conversion event and the network matches the sale back to the publisher.

What retailers actually pay

• A commission to the publisher — usually a percentage of the sale.
• A network fee on top — typically 20-30% of the commission value.
• The reader pays the same price either way. The commission comes out of the retailer's margin, not the reader's wallet.

Why we're transparent about this

Because there's an obvious potential conflict: if we make more money when we recommend a product, we could be tempted to recommend products we don't actually rate. Our answer is editorial independence — we cover the categories we know, we recommend the gear we would actually use, and we tell readers when the evidence is thin. Affiliate income funds the site; it doesn't decide what appears on it.

Takeaways

• Affiliate networks are the plumbing that lets publishers earn commissions on retailer sales.
• The reader never pays more; the commission is deducted from the retailer's margin.
• Transparency is the only thing that makes affiliate-funded publishing trustworthy — which is why we say all of this out loud.
